Is the oxygen machine and oxygen cylinder out of the same oxygen?
First of all, you can be sure that the oxygen machine and the oxygen cylinder out of oxygen are the same, the general oxygen concentration of the oxygen machine in more than 90%, the oxygen concentration of the oxygen cylinder in more than 99%, from the concentration of the oxygen cylinder is more concentrated.
Recommend oxygen cylinder for short-term use
Generally speaking, for short-term temporary oxygen intake, oxygen cylinders are the better choice. In fact, the oxygen cylinder has its unique advantages, which are high oxygen concentration, high flow rate, and good silence. The oxygen inside the cylinder is rushed in at high pressure at the filling station, so the oxygen pressure inside the cylinder is very high, and the oxygen flow can be adjusted to a high level.
There is another advantage of oxygen cylinders is "quiet", oxygen cylinder oxygen supply without additional noise, the use of very quiet, basically will not affect the patient rest.
There are advantages and disadvantages, the biggest disadvantage of oxygen cylinders is that they need to be replaced and inflated frequently, for those who live in remote places, it is not very convenient to inflate and change, if the patient's oxygen demand is high, then it may be necessary to change 2-3 bottles of oxygen a day, which is still relatively troublesome.
Why do I recommend the short-term priority use of oxygen cylinders? Because in the short term, the cost of oxygen cylinders is low, currently a bottle of oxygen is about 20 yuan, one bottle a day, almost 600 yuan a month, the cost of one or two months is not very high, but after a long time, it is not recommended to use oxygen cylinders for oxygen.
Long-term use of recommended oxygen machine
Generally more than half a year I recommend the use of oxygen machines, the reason is that long-term oxygen machines are cheaper and easier to use.
The molecular sieve of the oxygen machine can sieve out the nitrogen in our air, and the remaining gas is oxygen and very few rare gases.
The advantage of oxygen machine is that oxygen is inexhaustible, as long as the oxygen machine is not broken, then you can always have oxygen, do not need to be replaced and inflated as often as the oxygen cylinder. From a long-term perspective oxygen machine than oxygen cylinders to save money, the current price of a three-liter oxygen machine in about 3,000 yuan, as long as the oxygen intake time is higher than 6 months, then the cost of the oxygen machine than the cost of oxygen cylinders to be lower.
The disadvantage of the oxygen machine is that the sound is relatively large, the sound of oxygen machine operation is generally in the 40s of decibels, the sound is okay during the day, at night the sound is still quite loud, so it is a problem for patients who are sensitive to sound.
Another disadvantage of the oxygen machine is that the flow of oxygen is limited, like three liters of oxygen machine when the flow rate is adjusted to more than 3, the oxygen concentration will be reduced to 90%, and so on, five liters of oxygen machine is adjusted to more than 5 oxygen concentration will drop.
